ELECTRICAL SOUNDER.

SFECIFICATION forming part of Letters Patent No. 686,135, dated November5, 1901. Application filed April 17, 1901. Serial No. 56 305. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, ULYssEs G. Roenas, a citizen of the United States ofAmerica, and a resident of New York city, county and State of New York,have invented certain new and useful Improvements in ElectricalSounders, of which the following is a specification.

My invention consists of improvements in the construction of some of theparts of electrical sounders, whereby it is designed to provide simplerand cheaper construction, as hereinafter described, reference being madeto the accompanying drawings, in which- Figure 1 is a side elevation of.a sounder constructed in accordance with my invention. Fig. 2 is a planview of the base-plate inverted. Fig. 3 is a perspective view of thesounder-post. Fig. 4 is a perspective view of the lever-supportingstandard. Fig. 5 is an elevation of the upper-part of thelever-supporting standard as seen looking from the left hand of Fig. 1.

a represents the wood base; 19, the iron bar on which the spools c aremounted for connecting their cores, said bar being placed on the Woodbase and secured by the screws inserted through the wood base at d, thatalso secure the magnets, and by the screw at e,'that also secures thehind leg f of the sounderpost 9, said leg standing on said bar betweenthe spools of the magnet. The front leg h of the sounder-post is as muchlonger than the hind leg as the thickness of the iron bar and rests onthe Wood base forward of said bar and is secured by the screw at i.

The standard for supporting the pivot j of the lever is and thelever-retracting spring and adjusting devices comprises two legsl and anarch m, joining the upper endsof the legs,practically the same as inother sounders, except that the arch is abar of the same width as thelegs, and instead of being in the same plane as the legs, withrearwardly-projecting arm to support the lever-retracting spring 0 andits adj usting-screw n in their proper relation to the lever-axes, saidbar is curved backward to a suitable extent, as shown, so that the holein it for the adj usting-screw'n, being in the center of the bar,locates the spring 0 at the proper distance back of the lever-pivot.This not only saves the excess of'metal involved in the commonconstruction, but it afiords a form of the projecting side of the barmuch simpler and easier to finish by the grinding process, which is thepreferred method. I do not, however, claim this improvement of thepivot-supporting standard in this application, but I do claim it in adivisional application hereof. The legs 1 of the lever-pivot supportrest on the wood ba se-plate and are secured by the screw insertedthrough the base at 19. Thus it is to be seen that I provide simpler andcheaper sounders than such as are now made.

The iron bar and legs all placed on the wood base are thereby properlyinsulated;

What I claim as my invention is The combination in a telegraphicsounder, of the iron bar connecting the magnet-cores placed on thesurface of the wood base, the magnet-cores placed on the bar and securedthereto and together with the bar secured to the base by thecore-connecting screws insorted through the base and the bar, thesounder-post having the hind leg standing on the iron bar between themagnet-spools, and secured by a screw inserted through the base and thebar, and the front leg standing on the base and secured by a screwinserted through said base.
